In the Li Fire Realm, Heavenly Venerable Caiwei helped Li Yu extract the origin of the world and fuse it into his body.
After obtaining the origin of the Li Fire Realm, Li Yu became the master of this world and could control everything in it.
In this world, he possessed abilities similar to the Creator.
He could modify the operating laws, ecological forms, natural laws, and so on. Creation and destruction were only a matter of thought for him.
The power of the world's source was no longer unfamiliar to Li Yu.
Previously, he had fused with the natural source of the Lingtian Immortal Realm and was already familiar with using this power.
If not for the fact that the space in the Lingtian Immortal Realm was still unstable and that there were many hidden and unknown dangers, he would have long reshaped that place into an Immortal Realm and brought everyone from the Immortal Martial World to migrate.
